Additive effects of dexamethasone with PIK-294 on cytokine release in BAL cells from asthma patients (n = 10) and healthy subjects (n = 8). BAL cells were treated with varying concentrations of dexamethasone with or without 100nM of PIK-294 for 1 h before being stimulated with antibodies against CD3 and CD28 to induce a TCR-specific response. Cytokines were measured by ELISA. Data is presented as mean % inhibition (+/−SEM) of maximum cytokine release. Red line denotes inhibition by 100nM PIK-294 alone. Comparisons between with or without PIK-294 were analysed by 2-way ANOVA with Sidak post-test using cytokine levels: *p < 0.05; **p < 0.01; ***p < 0.001
